ENVELOPE FOR THE ,MA NUFACTUREiDF OIL-CAKE.

SPECIFICATION forming part of Letters Patent No. 224,135, dated February 3, 1880. Application filed July 26, 1879. Patented in England, October 24, 1878.

To all whom it may concern Be it known that we, CHARLES SPEoK BRITTAIN and HAROLD KING, both of Liverpool, in the county of Lancaster, in that part of the United Kingdom of Great Britain and Ireland called England, have jointly invented certain Improvements in Envelopes or Wrappers for the Manufacture of Oil-Cake, of which the following is a description in such full, clear, and exact terms as to enable any one skilled in the art or science to which it appertains to make and use the same, reference being had to the accompanying two sheets of drawings, making part of this specification.

Our invention relates to combined envelopes and wrappers for usein the extraction of oil by pressure from linseed and other oleaginous matters.

Hitherto it has been customary to press thesists of an outside case or coat, which can be of metal, mill-board, or other suitable substance; but We prefer American cotton duck. On this we place a series of ribs of wood or other tough material insoluble in oil. Hempen rope is a very good material for this purpose, and we now use it almost exclusively. Over this again, forming the inside of the wrapper, is or dinary woolen bagging;

The accompanying drawings (Figure 1 being a plan, with partof woolen bagging removed, and Fig. 2 section) show a combined envelope and wrapper fifteen inches wide by sixty long when new. The outside rope, A,

' is five-eighths of an inch, and the ribs Bin this case are formed by fifty-eight single folds of three-eighthsof-an-inch rope on each side the center. The cross-ropes are looped round the selvage rope. Between each fold of crossrope the covers of cotton duck D and woolen bagging G are tightly sewed together, inclosin g the rope between them. A space, E, of two inches clear of rope is shown in the center for the fold. Sometimes, instead of sewing the inside and outside envelopes together, with the rope or other bars between, we weave the whole in one, the bars taking the place of crossthreads at stated intervals, or are woven in by any other of the well-known modes.

The mode of using the envelope or wrapper is as follows: It is placed on a molding-machine and the requisite amount of oleaginous material measured out and compacted in'it by the machine. It is then taken to the hydraulic or other press, and pressed without the use of hairs, corrugated plates, or the like, the embedded ropes forming the ribs on the cake, besides aiding in the extraction of the oil by their capillary channels.

, We find this combined envelope and wrapper very economical on the following grounds First. It outlasts several ordinary wrappers.

Second. It is not as expensive as the ordinary hair and wrapper. It can be got into a smaller compass in the press, admitting of a larger number of cakes being pressed at one operation.

Our invention further consists in so manufacturing envelopes or wrappers with corrugations, as herelnbefore described, that the corrugation shall only appear on one side of the wrapper. This portion of our invention will be understood upon reference to Figs. 3, 4, and 5 of the drawings, in which Fig. 3 is an elevation of a portion of a sewing machine with a portion of a wrapper under manufacture. Fig. dis a plan of Fig. 3.- Fig. 5 is a portion of an envelope in sectional elevation.

a is a cloth of cotton canvas. 1) is a cloth of hogget, or wool, or hair. 01 is the table of a sewing-machine. e is the needle of a sewingmachine. f g are metal holder-bars.

It will be seenthat the cotton cloth ais flat. The woolen cloth b is corrugated. This is effected by filling in the pockets E with strips of pressed paper, wood, cane, rope, or any other suitable material, which is held in position, during the operation of stitching the cloths a, and b together, by the holders f g. The rows of stitching are represented I on the plan, Fig. 4, by the dotted lines h.

' We would have it understood that our invention of corrugated envelopes or wrappers can he applied to any kind of cake on which it is desired to produce a corrugated surface. We would also lnWe it understood that the pockets can be formed by stitching or weaving, and that the pockets can be filled in with rope, pressed paper, wood, cane, metal, or any other suitable hard material.

What we claim as our invention is- 1. A combined envelope and wrapper for pressing oil cake, consisting internally of woolen bagging and externally of cotton duck or otherknown material used for this purpose, united together over the inelosed bars to form the combined envelope and wrapper, substantially as herein described.

In testimony whereof we have hereunto 20 signed our names.
